BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a concentrated hormone pharmaceutical composition to be used in the production of hormone replacement therapies.

2. Description of the Related Art

Natural Hormone Replacement Therapy has been around for more than twenty years. The term “natural” comes from the fact that the hormones (estrogens such as estradiol, estrone, and estriol, testosterone, DHEA, pregnenolone and progesterone) come from natural sources. However, more importantly, the term means that the hormones have the exact same molecular structure as those produced by the body itself, thus the body recognizes the hormones as being “natural”, because they are “bio-identical”, therefore, the shift to a more appropriate name, Bio-identical Hormone Replacement Therapy (BHRT).

Some of the benefits of BHRT include: fewer side effects compared with traditional HRT; protection against heart disease, reduced risk of breast cancer, and improved lipid profile.

Bio-identical Hormone Replacement Therapy products are compounded by a compounding pharmacist, which offers you and your physician a choice for individualized hormone replacement. Generally the BHRT pharmaceutical compositions are sold in the form of ointments, creams, gels, pastes, capsules, troches, lozenges, lollipops, tablet triturates, sublingual tablets, and tablets.

A BHRT ointment, cream, gel, or paste may include, but is not limited to, the active hormone or hormones, a suitable solvent or solvents, including, but not limited to, ethoxy diglycol, propylene glycol, alcohol, or glycerin and any suitable ointment, cream, or gel base which allows for transdermal absorption of bio-identical hormones.

Producing BHRT pharmaceutical compositions is a very lucrative business for compounding pharmacies. However, the process of producing the BHRT pharmaceutical compositions is an extremely time-consuming process and has many risks and subsequent costs associated with the compounding of BHRT pharmaceutical compositions.

One of the main problems with compounding BHRT pharmaceutical compositions is the substantial risk of employee contamination (inhalation or transdermal absorption of the hormones) with the hormones. The hormones used for producing the BHRT pharmaceutical compositions are naturally found in the body in physiological levels. Thus, when a human is chronically exposed to higher than normal levels of these hormones, they are at risk of developing serious adverse medical effects, including, but not limited to, an unnatural increased response by each system of the body which is affected by each individual hormone, as well as an increased risk of developing numerous varieties of cancer.

In addition, producing these BHRT pharmaceutical compositions requires great skill and knowledge. It also requires expensive equipment such as accurate electronic scales, electronic mortars and pestles (EMP), and ointment mills.

In order to diminish these risks, the compounding pharmacies have developed an expensive and time-consuming method to reduce employee exposure to these hormones. These measures include, but are not limited to, the use of a custom built clean room, high velocity air flow units fitted with high emission particulate air (HEPA) filters, custom built ventilation systems, protective suits, protective eyewear, protective gloves, and protective HEPA filter masks.

The production of BHRT pharmaceutical compositions is by itself a time-consuming process. Each ointment, cream, gel, or paste must be specifically engineered for each patient based on his or her distinct hormone profile, thus the use of bulk compounding is precluded, because each medication is produced custom fit for each patient.

Furthermore, bulk compounding or manufacturing of hormone products is illegal in most states without a proper license.

In order to produce these BHRT pharmaceutical compositions safely and accurately, compounding pharmacies need to invest a great deal of time and money into these safety measures. The pharmacies would also need to employ a specially trained staff; all these measures decrease productivity substantially.

These measures are not only expensive, but also create an unpleasant work environment. This is due to the fact that the employee is covered from head to toe in restrictive, uncomfortable protective gear. They are also working in a room, which is noisy because of the high velocity ventilation systems, which are in constant use.

In order to work with BHRT pharmaceutical compositions, an employee must:

Be trained in the art of compounding BHRT ointments, creams, gels, and pastes.

Ensure they are wearing all the necessary protective gear.

Locate all of the ingredients.

Weigh all of the ingredients in the appropriate environment, a clean room with proper ventilation and filtration systems, to prevent exposure to harmful chemicals.

Combine the ingredients using the EMP to ensure thorough mixing. If the mixture is not thoroughly mixed, then it will not contain a uniform concentration of the drug throughout.

Run the mixture through an ointment mill to decrease the particle size of the drug. This will increase absorbability, as smaller drug particles will more readily penetrate the dermis. This process also ensures a non-gritty, pharmaceutically elegant, and cosmetically pleasing final product.

The combination of the potential risks associated with producing BHRT pharmaceutical compositions, specially trained employees to compound these compositions safely and accurately, purchasing all the necessary equipment and safety measures, and the actual time required to compound each individual pharmaceutical composition result in an extremely time-consuming, hazardous, and expensive process.

The present inventor thought of the necessity of providing pharmacies with a system that is easy to use and saves time and money for those pharmacies dealing with BHRT pharmaceutical products while decreasing risk and increasing product quality.

Solvent (or Wetting Agent)

The solvent or wetting agent can be any liquid that can dissolve, partially dissolve, wet, or suspend the hormone, or reduce the surface tension of a liquid to a value below the hormones critical surface tension.

In order for a solid to be incorporated into a liquid, the solids surface tension must be above the surface tension of the liquid. The best solvents produce a low air liquid surface tension, and are not readily adsorbed by the solid so as to produce nonwetting behavior.

The wetting agent or solvent acts by lowering the contact angle between the surface of the particle and the wetting liquid. Wetting agents replace a solid to air interface with a solid to liquid interface. The solvent or wetting agent should be miscible with the carrier.

The solvent or wetting agent could possibly be, but is not limited to, one or more of the following in any concentration: propylene glycol, ethoxy diglycol, glycerin, mineral oil, fixed oil, emu oil, peanut oil, vitamin E oil, acetone, amylene hydrate, benzyl benzoate, corn oil, cottonseed oil, diethylene glycol monoethyl ether, ethyl acetate, isopropyl alcohol, methyl alcohol, methylene chloride, methyl isobutyl ketone, polyethylene glycol 300, polyethylene glycol 400, polyethylene glycol 600, sesame oil, alcohol, a 50% ethoxy diglycol (diethylene glycol mono-ethyletherand) 50% propylene glycol mixture, water or mixtures thereof. Any combination of solvents may be employed.

The solvent or wetting agent should satisfy the following characteristics:

the solvent or solvents should wet the hormone;

the solvent should allow the hormone to be incorporated therein;

the solvent or solvents should be compatible with the skin with the least possible number of adverse effects;

the solvent or solvents should be smooth and pliable with no adverse odor;

the solvent or solvents should have a color appealing to the consumer; and the solvent must be stable and must provide a stable vehicle for the medication.

The scope of the present invention is not limited by the solvents mentioned in the present application; any of those known in the pharmaceutical and cosmetic industries may be employed.

Pharmaceutically Acceptable Carrier

The carrier can be any suitable carrier that can be incorporated into a system, which can deliver bio-identical hormones transdermaly.

The formulations for the delivery of the pharmaceutical composition according to the present invention may be liquid, ointments, and creams.

The carrier can be chosen from ointment base, powder base, cream base, or a gel base.

Ointments are semisolid preparations, which are typically based on petrolatum or other petroleum derivatives. Creams containing the selected active agent, are, as known in the art, viscous liquid or semisolid emulsions, either oil-in-water or water-in-oil.

Cream bases are water-washable, and contain an oil phase, an emulsifier, and an aqueous phase. The oil phase, also sometimes called the “internal” phase, is generally comprised of petrolatum and a fatty alcohol such as cetyl or stearyl alcohol; the aqueous phase usually, although not necessarily, exceeds the oil phase in volume, and generally contains a humectant.

The specific ointment or cream base to be used, as will be appreciated by those skilled in the art, is one that will provide for optimum drug delivery. As with other carriers or vehicles, an ointment base should be inert, stable, nonirritating and non-sensitizing.

Powders may be formulated with the aid of any suitable powder base, such as talc, lactose, starch, and the like.

In a further embodiment of the present invention, the hormone is weighed and packaged unadulterated in an appropriate container. The solvent or solvents and/or optionally the ointment, cream, gel base, or powdered base are packaged in a separate container. The two products are sold together as a kit. The two components are to be combined by whoever purchases the kit to formulate the hormone concentrate system.

Color Coded-concentrated Pharmaceutical Composition

The present invention also provides a color-coded concentrated hormone composition to help the pharmacist quickly choose the composition to be used.

The advantage of having color-coded concentrates are as follows:

helps to rapidly identify the concentrate.

ensures that all concentrates required to be contained in a final product are present in said final product. This is made possible because each combination and permutation of the concentrates will result in a distinct color profile. If the final product does not match the color profile for that medication, you know you have done something wrong; and

ensures complete mixing of the final product. When the final product is a uniform color throughout, adequate mixing will have taken place.

The coloring agent could possibly be, but is not limited to one of the following: acid red 52, basic fuchsin USP, brilliant green, caramel NF, carmine NO. 40, congo red, D&C green NO. 5, D&C green NO. 6, D&C green NO. 8, D&C orange NO. 4, D&C red NO. 4, D&C red NO. 6, D&C red NO. 17, D&C red NO. 22, D&C red NO. 28, D&C red NO. 33, D&C violet NO. 2, D&C yellow NO. 8, D&C yellow NO. 10, D&C yellow NO. 11, F.D. &C. blue NO. 1, F.D. &C. blue NO. 2, F.D. &C. green NO. 3, F.D. &C. red NO. 3, F.D. &C. red NO. 19, F.D. &C. red NO. 40, F.D. &C. yellow NO. 5, F.D. &C. yellow NO. 6, malachite green oxalate, rose Bengal, saffron, scarlet red, and any food color in liquid or powder form. The coloring agent is not particularly limited; any of those known in the pharmaceutical or cosmetic industries may be employed. Preferably, the coloring agent will not noticeably color the skin. It should be compatible with the skin with the least number of adverse effects.

The concentrates according to the present invention would be manufactured using extensive safety measures. These include, but are not limited to, the use of custom built clean rooms (a room designed specifically for compounding with hazardous materials), high velocity air flow units fitted with high emission particulate air (HEPA) filters, custom built ventilation systems, protective suits, protective eyewear, protective gloves, and protective HEPA filter masks.

A pharmacist or technician trained in the art of compounding BHRT ointments, creams, gels, and pastes will manufacture these concentrates.

An advantage of the present invention is the composition contains a high concentration of hormones (higher than the prescribed levels), thus the pharmacist can easily use the concentrates to produce a custom tailored BHRT product without risking his own health.

The present invention also contemplates a method for producing the concentrated composition of the present invention. The method comprises the steps of:

measuring at least one hormone, a solvent and/or optionally a carrier by using an electronic balance in a clean room;

combining the ingredients of step a by using an industrial scale mixer to ensure thorough mixing; and

running the mixture of step b through a large-scale ointment mill or homogenizer to decrease the particle size of the drug, and

optionally, heating the concentrate to facilitate the formation of a solution, wherein the hormone concentration is from about 0.6 to about 80%.

The concentrated hormone pharmaceutical composition of the present invention may be further divided with similar or different carrier materials to concentrations that are suitable for practical use by the compounding pharmacist.

If the medication is not thoroughly mixed, then it will not contain a uniform concentration of the drug throughout. A solution will provide the best distribution of drug throughout the system.

Running the mixture through a large-scale ointment mill or using a homogenizer decreases the particle size and increases the absorbability, because smaller drug particles will more readily penetrate the dermis. This process also ensures a non-gritty, pharmaceutically elegant, and cosmetically pleasing final product.

The present invention is also in combination with a dispensing device to provide a means to measure and combine, quickly and accurately, quantities of hormones with appropriate ointment, cream, or gel bases while minimizing exposure to hazardous airborne hormone particles. Thus, airborne particles are drastically reduced because the hormones are incorporated into a liquid or semi-solid form.

This is what the mixture is sold in.

The mixture of example 11 will be sold as a kit in which the pharmacist will combine the elements to produce the hormone concentrate system. The pharmacist will transfer the liquid into the bottle containing the estriol, then transfer this mixture into the bottle containing the estradiol, then transfer this mixture into the bottle containing the estrone. This final solution will be the triest concentrate.

These concentrates could be packaged in, or with, any graduated dispensing device that lends itself to accurately measure specific volumes of liquids or semi-solids including, but not limited to, a metered dose tube, a metered dose pump, a metered dose syringe, a bottle, an ointment jar, a metered dose spray bottle, a bottle fitted with an adapter cap, and a luer lock syringe, a pipette, a bottle top dispenser, a burette, and a metered dose scoop. The packaging, dispensing, or measuring devices are not particularly limited. Any of those known in the pharmaceutical, chemical, or cosmetic industries may be used.

A specific amount, different for each compound, of these concentrates would be combined with an appropriate amount of any ointment, cream, or gel base, suitable for transdermal administration of bio-identical hormones, to form a final product which contains the doctor prescribed concentration of each bio-identical hormone.

The pharmacist using the concentrate, according to the invention, can easily incorporate the hormone into the compounding BHRT ointments, creams, gels, or pastes by:

Putting on protective gloves.

Calculating the total amount of hormones needed to compound a medication of a specific volume and concentration depending on the patient necessities;

Determining how many milliliters of the appropriate concentrate will contain the total amount of hormone needed for the compound.

Measuring the volume of concentrate containing the total amount of hormone needed. This is done using an appropriate liquid or semi-solid measurement system.

Repeating steps 2 through 4 for each hormone to be present in the final preparation.

Calculating the amount of the appropriate ointment, cream, or gel base, which is needed for the final product. This is accomplished by subtracting the total volume of concentrates used from the total volume needed.

Combining the ointment, cream, or gel base and the concentrates on a glass ointment slab, using an EMP, mixing them an appropriate number of times between two luer lock syringes attached together using a luer lock to luer lock adapter or any other form of mixing. When the color is uniform throughout, adequate mixing has taken place.

In another embodiment, the pharmaceutically acceptable carrier is sold inside a metered dose device. These will make unnecessary to use a scale in measuring and making BHRT creams. This is a distinct advantage for pharmacies not presently engaged in the art of compounding. The only additional equipment needed is a spatula for mixing. If the carrier is not packaged in a metered device, then the cream would have to be weighed and measured using a scale, which takes more time as well as additional cost to purchase the scale.

In addition, the invention concerns a kit for producing a concentrated hormone pharmaceutical composition, the kit comprising:

at least one hormone;

at least one solvent, and

optionally a pharmaceutically acceptable carrier,

wherein each element is packet in separated graduated dispensing devices.

In a further embodiment, the kit of the present invention comprises separately packing the at least one hormone and the at least one solvent in a container having internal divisions, wherein the at least one hormone and the at least one solvent are combined by the purchaser to form the hormone concentrate system.

Advantages

The concentrated composition of the invention offers numerous advantages over compounding BHRT ointments, creams, gels, or pastes using a traditional method with commercially available hormones in powder form.

Using these concentrates, combined with an appropriate liquid or semi-solid measurement system, in the place of powdered hormones and a scale, will dramatically reduce the risk of exposure to hazardous airborne hormone particles. This is due to the fact that the powdered hormones are incorporated into a liquid or semi-solid. This means that the need for inconvenient, expensive, and time-consuming safety measures is greatly reduced. Since there are relatively few airborne particles, there is little or no need for the use of custom built clean rooms (a room designed specifically for compounding with hazardous materials), high velocity air flow units fitted with HEPA filters, custom built ventilation systems, protective suits, protective eyewear, or protective HEPA filter masks. The only safety measure definitely required is protective gloves.

When the concentrates are manufactured, they are mixed using an industrial mixer, which ensures thorough mixing. This alleviates the need for purchasing and using an EMP for compounding BHRT ointments, creams, gels, or pastes. They are also run through a large ointment mill or homogenizer to reduce the particle size of the drug. This will increase absorbability, as smaller drug particles will more readily penetrate the dermis. This process also ensures a non-gritty, pharmaceutically elegant, and cosmetically pleasing product. This alleviates the need for purchasing and using an ointment mill for compounding BHRT ointments, creams, gels, or pastes.

The concentrates of the present invention offer the advantage that they are easier and most accurate to measure. The fact that the hormones are in solution results in a superior final product, the product produced from the concentrates and dispensed to the patient. This is due to the fact that there are no particles. All particles have been solubilized. This results in a pharmaceutically elegant and easily penetrateable final product.

The fact that the concentrates are color-coded will greatly reduce the chance of compounding errors. The color system should reduce the inadvertent use of one hormone concentrate instead of another. It will also ensure that all of the intended concentrates are present in the final product. This is accomplished because each combination and permutation of the concentrates will have a distinct color profile. If the final product does not match its profile, then you know something has been done incorrectly. The color system will also help ensure that the final product is uniformly mixed. When the final product is a consistent color throughout, you will have adequate mixing. At the present time, most compounding pharmacists do not have an adequate system in place to ensure proper mixing. Without proper mixing, the final product will not have a uniform concentration of the hormones throughout the system.

Since the concentrate system alleviates the need for most of the safety measures required for compounding these medications, as well as the need for a scale, EMP, and ointment mill, it significantly reduces the cost of compounding these. medications. The concentrate system also significantly decreases the time needed to compound them. This is because the number of steps needed to compound them is drastically reduced. This increase in efficiency will result in a proportional decrease in labor costs.

The hormone concentrates and an appropriate liquid or semi-solid measurement system will make it possible for any pharmacist in any setting to safely and accurately compound BHRT ointments, creams, gels, and pastes. At the present time, only compounding pharmacists with elaborate compounding facilities and the proper equipment can compound them safely and accurately. Using this invention, any pharmacist in any setting will now be able to safely, quickly, inexpensively, and accurately compound BHRT ointments, creams, gels, and pastes. This will inevitably result in an increase in the availability of these medications to the public.

The fact that each final product, the product dispensed to the patient, has a distinct colour profile has an additional benefit. It will help decrease the chance of dispensing the wrong product to a patient. If a patient was to receive a Tri-est cream (which should be pink) but a blue cream was labeled Tri-Est, the pharmacist would be easily able to identify the error. Also, the patient would be able to tell that their previous cream was pink and this one is blue, bringing this to the pharmacist's attention. At present time all hormone creams are white, making it all but impossible to detect a labeling error. The colour coding also decreases the likely hood of choosing the wrong cream from the stock as each cream is readily identifiable. The coloring system allows each final product to be differentiated from one another.
